The method for balancing the load of the stateful server provided by the present application can be applied to the application environment shown in fig. 1, where fig. 1 is a schematic diagram of an application environment of a method for balancing the load of the stateful server according to an embodiment of the present application, and as shown in fig. 1, a system of the application environment includes a server 10 and a smart terminal device 11, where the server 10 obtains a free server in a backend server, the free server is a first server, then allocates a game resource to the first server through a setex instruction of redis, then connects the game resource to the first server for service, and within a preset interval time, the first server continues to be in a binding relationship with the game resource through redis, and finally, in a case that there is no continuation time after the preset time in the redis, the binding relationship between the first server and the game resource expires, and the game resource applied to the smart terminal device 11 is reallocated, the problems that when game resources are distributed in a server with a state, load distribution is uneven, a single-point fault occurs in the system, and dynamic expansion of the server is difficult are solved, dynamic load balance of the game resources is achieved, dynamic expansion of the server is achieved, and the single-point fault of the system is eliminated.
Fig. 2 is a flowchart of a load balancing method for a stateful server according to an embodiment of the present application, and as shown in fig. 2, the flowchart includes the following steps:
step S201, acquiring an idle server in the back-end servers, where the idle server is a first server, and optionally, assuming that there are 3 servers that can serve at the back-end, in this embodiment, a relatively idle server in the 3 back-end servers is selected, and the idle server is the first server. Compared with the prior art that a hash mode is adopted for load balancing distribution, the embodiment can directly add a back-end server outside to realize dynamic capacity expansion of the server;
step S202, game resources are distributed to a first server through a setex instruction of the redis, wherein the redis is a key value pair storage database which comprises various data structures, a supporting network, a memory base and optional persistence, in addition, the setex instruction of the redis is used for appointing timeout in a redis key, and character string values of the key are set, namely appointing key set values and the expiration time thereof, for example, setex A60S, wherein A represents game resources, S represents the first server, and 60 represents the expiration time of 60 seconds. Fig. 3 is a schematic diagram of dynamically allocating a backend server according to an embodiment of the present application, and as shown in fig. 3, optionally, in this embodiment, game resources a, such as players, meetings, and the like, are allocated to a first server S through a setxa 60S instruction of redis. In the embodiment, game resources are allocated to the first server through the redis cluster, and compared with the situation that a single point fault is generated when load resources are allocated through a central server in the prior art, the problem of the single point can be effectively avoided through the redis cluster, namely when a master node and a slave node have faults, the slave node can replace a fault master node to perform service;
step S203, connecting the game resource to a first server for service, and within a preset interval time, continuing the first server through a binding relationship between the redis and the game resource, optionally, in this embodiment, after the game resource is notified by the system and allocated to the first server, the game resource is connected to the first server for service, and at intervals of a period of time, for example, 30 seconds, the first server will continue the service through the binding relationship between the redis and the game resource a;
step S204, when the preset time in the redis is not expired, the binding relationship between the first server and the game resource expires, and the game resource is reallocated, optionally, in this embodiment, when the preset 60 second expiration time in the redis is not expired, the binding relationship between the first server S and the game resource a expires, and at this time, the game resource a is reallocated to another server. In the embodiment, an atomic operation is realized through the lua script of the redis, that is, the game resources are dynamically allocated, so that the dynamic load balance of the resources can be realized.
Through the steps S201 to S204, compared with the prior art, the problem that the dynamic expansion of the server is difficult and the load distribution is uneven when the stateful server realizes the load balance in a hash manner; and load distribution is performed through one central server, so that the problem of single-point failure of the server can exist. In this embodiment, an idle server in the backend server is obtained, where the idle server is the first server, the game resources are then allocated to the first server by the setex instruction of the redis, then connecting the game resource to a first server for service, and in a preset interval time, the first server continues for a period through the binding relationship between the redis and the game resource, and finally, under the condition that the period is not continued after the preset time in the redis, when the binding relationship between the first server and the game resource is expired, the game resource applied to the intelligent terminal device 11 is redistributed, thereby solving the problem that when the game resource is distributed in the stateful server, the problems of uneven load distribution, single-point failure of the system and difficulty in dynamic capacity expansion of the server are solved, dynamic load balance of game resources is realized, dynamic capacity expansion of the server is realized, and the single-point failure of the system is eliminated.
In some embodiments, before the game resource is connected to a first server for service, a server where the game resource is currently located is always obtained through a get instruction of redis, where the server is a second server, the get instruction of redis is used for obtaining a value of a specified key, and if the key does not exist, nil is returned; if the key stores a value other than the string type, an error is returned, e.g., get A refers to the second server where game resource A is currently located. Optionally, because concurrent operation is performed, that is, when an account of one game player logs in on two terminal devices, the game resource a (player account) at this time is allocated to a second server, which is different from the first server, before the game resource a is connected to the first server for service, the second server where the game resource a is currently located needs to be always obtained through a get a instruction of redis, which is beneficial to being connected to the second server where the game resource a is actually located in subsequent resource connection.
In some embodiments, obtaining a free server in the backend server comprises: and acquiring the ID of the idle server stored in the redis, and positioning the idle server by a service discovery protocol through the ID, wherein the service discovery protocol is various, such as Consul, Zookeeper, Etcd, Eureka and the like. Optionally, the system process obtains an ID of the idle server stored in the redis, and the service discovery protocol locates the obtained idle server through the ID by using a load balancing algorithm such as a polling method, a random sending method, a hash method, a minimum connection number, a weight, and the like. In addition, as long as the system process is started, the newly added back-end server can be obtained through the service discovery protocol.
In some embodiments, the expiration of the binding relationship of the first server to the game resource comprises: and when the first server is down or the game player logs out, the binding relationship between the first server and the game resources is expired. Optionally, when the server goes down or the game player account logs out, the binding relationship between the server and the game resources may expire, and the game resources may be reallocated.
It should be noted that the steps illustrated in the above-described flow diagrams or in the flow diagrams of the figures may be performed in a computer system, such as a set of computer-executable instructions, and that, although a logical order is illustrated in the flow diagrams, in some cases, the steps illustrated or described may be performed in an order different than here.
The present embodiment further provides a system for load balancing of a stateful server, where the system is used to implement the foregoing embodiments and preferred embodiments, and details of the system that have been already described are omitted. As used hereinafter, the terms "module," "unit," "subunit," and the like may implement a combination of software and/or hardware for a predetermined function. Although the means described in the embodiments below are preferably implemented in software, an implementation in hardware, or a combination of software and hardware is also possible and contemplated.

Compared with the prior art that the acquisition module 41 performs load balancing distribution by adopting a hash mode, the module of the embodiment can be directly externally added with a back-end server to realize dynamic capacity expansion of the server; the allocation module 42 allocates the game resources to the first server through the redis cluster, and compared with the prior art that a single point fault is generated when load resources are allocated through a central server, the problem of the single point can be effectively avoided through the redis cluster, that is, when a master node and a slave node have a fault, the slave node can replace a fault master node to perform service; the timing renewal module 43 may be configured to connect the game resource to the first server for service after the game resource is informed by the system to be allocated to the first server, and the first server may renew the game resource a through a binding relationship between redis and the game resource a at an interval of time, for example, 30 seconds; the redistribution module 44 implements an atomic operation through the lua script of the redis, that is, dynamically distributes the game resources, and can implement dynamic load balancing of the resources. The whole system solves the problems of uneven load distribution, single-point fault of the system and difficulty in dynamic expansion of the server when game resources are distributed in the stateful server, realizes dynamic load balance of the game resources and dynamic expansion of the server, and removes the single-point fault of the system.
In some embodiments, the allocating module 42 is further configured to, before the game resource is connected to a first server for serving, always obtain, by a get instruction of redis, a server where the game resource is currently located, where the get instruction of redis is used to obtain a value of a specified key, and if the key does not exist, return to nil; if the key stores a value other than the string type, an error is returned, e.g., get A refers to the second server where game resource A is currently located. Optionally, because concurrent operation is performed, that is, when an account of one game player logs in on two terminal devices, the game resource a (player account) at this time is allocated to a second server, which is different from the first server, before the game resource a is connected to the first server for service, the second server where the game resource a is currently located needs to be always obtained through a get a instruction of redis, which is beneficial to being connected to the second server where the game resource a is actually located in subsequent resource connection.
In some embodiments, the obtaining module 41 is further configured to obtain an ID of an idle server stored in the redis, and the service discovery protocol locates to the idle server through the ID, where the service discovery protocol is many, for example, Consul, Zookeeper, Etcd, Eureka, and the like. Optionally, the system process obtains an ID of the idle server stored in the redis, and the service discovery protocol locates the obtained idle server through the ID by using a load balancing algorithm such as a polling method, a random sending method, a hash method, a minimum connection number, a weight, and the like. In addition, as long as the system process is started, the newly added back-end server can be obtained through the service discovery protocol.
In some embodiments, the redistribution module 44 is further configured to, in the event that the first server is down or the game player logs out, expire the binding relationship between the first server and the game resource, and optionally, in the event that the server is down or the game player account logs out, expire the binding relationship between the server and the game resource, and reallocate the game resource.
